摘要
架空型线路故障指示器能识别架空线发生的接地和短路故障,是智能电网的重要组成部分.针对传统故障指示器存在的问题,设计了一种智能新型架空型故障指示器.该指示器采用低功耗单片机、电流互感器、LoRa远传技术以及锂电池备用电池,可实现长时间远距离传输以及低功耗监测接地和发现短路故障,具有高可靠性、低耗能、智能化的特点.
Abstract
The overhead line fault indicator can identify ground and short-circuit faults occurring on overhead lines,and is an important component of a smart grid.In this article,we have designed a new intelligent overhead line fault indicator in response to the problems with traditional fault indicators.The new indicator features low-power microcontrollers,current transformers,Long Range Radio(LoRa)technology and lithium-ion backup batteries,enabling long-term,long-distance transmission and low-power monitoring of ground and short-circuit faults detected,with characteristics including high reliability,low energy consumption,and intelligence.
